Manufacturing method of large-specification aluminum alloy composite material with width of 1500 mm or above

Abstract

The invention relates to a manufacturing method of an aluminum alloy composite material, and especially relates to a manufacturing method of a large-specification aluminum alloy composite material with the width of 1500 mm or above. The problem that the thickness of the edge of a coating layer formed by a skin material in the large-specification aluminum alloy composite material manufactured through an existing method is small is solved. The method comprises the steps that a layer of skin material and a layer of core material are stacked, or two layers of the skin material and the layer of the core material are stacked, the core material is arranged between the two layers of skin materials, hot rolling is conducted after heating, and chamfers are arranged on the edges of the upper surface and the lower surface of the core material in the length direction. The method is suitable for production of the large-specification aluminum alloy composite material with the width of 1500 mm or above, accurate matching of the skin material and the core material is adopted, the thickness, the side face shape and the milling face angle and width of a core material cast ingot are quantified, it can be guaranteed that metal flowing is in a controlled state in the compounding process, and the conditions that the leather material deflects and extends due to the large specification, and the thickness of the edge of a coating layer formed by the leather material is not uniform are avoided.

Description

technical field [0001] The invention relates to a method for manufacturing an aluminum alloy composite material. Background technique [0002] With the development of science and technology and the progress of human development, the market demand for large-scale air separation equipment suitable for metallurgy, petrochemical, coal chemical, chemical fertilizer, non-ferrous smelting and other fields continues to expand. Large-scale air separation equipment uses air separation technology to compress air at high density, and then uses the difference in the condensation point of each component in the air to separate the gas-liquid components at a certain temperature. Large-scale air separation equipment is mainly used in Metallurgy, petrochemical, coal chemical and other industries, and with the increase in production scale, the demand for high-quality raw materials is increasing year by year. [0003] Large-scale air separation equipment is mainly made of large-scale aluminum ...
